Q1: Does it have a mac driver?
A: Yes, the driver installation profile includes mac driver.
Q2: I need to use this on my tv to add wifi will it work?
A: This is not wifi, this is a adapter to accept a wifi signal. It will accept two different frequencies, and should not be a problem with your smart TV as long as you have a wifi + modem. Also remember all these adapters have drivers, so if you have a means of adding a driver to your TV, than it will work. Most of TV already have built in adapter, but this adapter will not provide a wifi signal that is a separate item that will work in conjunction with your modem.
